frequency-info -------------- analyzing CPU 8: driver: amd-pstate-epp CPUs which run at the same hardware frequency: 8 CPUs which need to have their frequency coordinated by software: 8 maximum transition latency: Cannot determine or is not supported. hardware limits: 400 MHz - 4.27 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 4.27 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 4.24 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes AMD PSTATE Highest Performance: 166. Maximum Frequency: 4.27 GHz. AMD PSTATE Nominal Performance: 140. Nominal Frequency: 3.60 GHz. AMD PSTATE Lowest Non-linear Performance: 93. Lowest Non-linear Frequency: 2.39 GHz. AMD PSTATE Lowest Performance: 16. Lowest Frequency: 400 MHz. idle-info --------- CPUidle driver: acpi_idle CPUidle governor: menu analyzing CPU 8: Number of idle states: 4 Available idle states: POLL C1 C2 C3 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 1203587 Duration: 28960410 C1: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Usage: 59146640 Duration: 6933036487 C2: Flags/Description: ACPI IOPORT 0x414 Latency: 18 Usage: 104276927 Duration: 28696525464 C3: Flags/Description: ACPI IOPORT 0x415 Latency: 350 Usage: 87746491 Duration: 506470721320
